The BT 3.0 Amplifier Module offers a seamless way to upgrade your audio system with wireless Bluetooth streaming, bringing modern convenience to traditional passive speakers. This compact booster module is ideal for DIY enthusiasts, custom installations, or anyone looking to add Bluetooth capability to an existing stereo setup without the bulk of a full-sized receiver. Whether you are building a bespoke bookshelf speaker system, revitalising vintage speakers, or creating a multi-room audio solution, this module delivers reliable performance in a space-saving design.

Technically, the module provides impressive power output that scales with your DC supply voltage. At 12 VDC, it delivers 10+10W into 8 ohms or 15+15W into 4 ohms, rising to 23+23W at 8 ohms and 40+40W at 4 ohms with a 19 VDC supply. For maximum performance, a 22–24 VDC input yields up to 32+32W at 8 ohms or a substantial 50+50W at 4 ohms. The input sensitivity is rated at 500 mV, ensuring compatibility with a wide range of audio sources. With Bluetooth 3.0 connectivity, you can stream music wirelessly from smartphones, tablets, or laptops directly to your speakers. This module is a practical, high-value solution for adding versatile wireless audio to any passive speaker system.
